Really helpful Jjaycee - really appreciate that list - and yes I will be getting Southampton whilst it's in the sale!!!
Is the GB Central library in the sale as well??…….mind you, I'll be checking that one out!
I'll also now be having to upgrade my graphics card!!! I knew I'd have to if I bought this scenery as at best I'm only getting sub 25fps on my current built in graphics. To my surprise, taking off from Exeter, my frame rate was similar......until I got near to Bristol or any other major town which made things go a little juttery. Still - a good excuse now to get that upgrade....
I'm seeing the Orbx plugin recognised within the plugin tab in flight, so I know it's all gone in smoothly. And it's been working without the need for me to tweak anything, but bearing in mind the Southampton airport is on the cards, your rule of thumb list is really appreciated.
